The LPC port can be used to connect a super I/O device,
or for an alternate flash EPROM to start with a corrupted
or blank flash EPROM on board. These pins can also be
reprogrammed as GPIO (not tested): Clear PMR pin
multiplex register (I/O 09030h) bit 14 and 16, then set
correct GPIO direction (input / output). Please see the
SC1100 data sheet for details.
